Patent number: 8969639Abstract: In a dehydrogenation process a hydrocarbon stream comprising at least one non-aromatic six-membered ring compound and at least one five-membered ring compound is contacted with a dehydrogenation catalyst produced by a method comprising treating the support with a liquid composition comprising the dehydrogenation component or a precursor thereof and at least one organic dispersant selected from an amino alcohol and an amino acid. The contacting is conducted under conditions effective to convert at least a portion of the at least one non-aromatic six-membered ring compound in the hydrocarbon stream to benzene and to convert at least a portion of the at least one five-membered ring compound in the hydrocarbon stream to paraffins.Type: GrantFiled: December 17, 2010Date of Patent: March 3, 2015Assignee: ExxonMobil Chemical Patents Inc.Inventors: Teng Xu, Stuart L.

Publication number: 20140330058Abstract: A process is described for producing a catalyst composition comprising an iridium component dispersed on a support. In the process, silica-containing support is treated with an iridium compound and an organic compound comprising an amino group to form an organic iridium complex on the support. The treated support is then heated in an oxidizing atmosphere at a temperature of about 325° C. to about 475° C. to partially decompose the organic metal complex on the support. The treated support is then heated in a reducing atmosphere at a temperature of about 350° C. to about 500° C. to convert the partially decomposed organic iridium complex into the desired iridium component.Type: ApplicationFiled: July 21, 2014Publication date: November 6, 2014Inventors: Stuart L. Soled, Sabato Miseo, Joseph E. Baumgartner, Christine E. Kliewer, Jane C. Cheng

Patent number: 8536085Abstract: A method is provided for preparing a supported cobalt-containing catalyst having substantially homogeneously dispersed, small cobalt crystallites. The method comprises depositing cobalt nitrate on a support and then subjecting the support to a two-step decomposition protocol. In the first step, the support is heated in an oxygen-containing, substantially water-free atmosphere to about 160° C. to form an intermediate decomposition product. This intermediate product is then or hydrolyzed and reduced, or hydrolyzed, calcined and reduced.Type: GrantFiled: October 24, 2011Date of Patent: September 17, 2013Assignee: ExxonMobil Research and Engineering CompanyInventors: Stuart L. Soled, Joseph E. Baumgartner, Christine E. Kliewer, El-Mekki El-Malki, Patricia A. Bielenberg

Patent number: 7585808Abstract: The present invention is directed to processes for preparing supported metal catalysts comprising one or more catalytically active metals applied to a porous catalyst support and to processes that use such catalysts. The process requires the formation of an organic complex during the manufacture of the catalyst which after its formation is either partially or fully decomposed before reduction if the metal to form the catalyst. The catalysts have high levels of metal dispersion and uniform distribution of catalytically active metals on the support. The catalysts obtained form the processes are particularly effective in catalysing Fischer-Tropsch reactions and as adsorbants for the removal or organosulfur compounds from hydrocarbons.Type: GrantFiled: November 18, 2003Date of Patent: September 8, 2009Assignee: ExxonMobil Research and Engineering CompanyInventors: Andrzel Malek, James Clarke Vartuli, Stuart Leon Soled, Sabato Miseo, Jennifer Schaefer Feeley, Gary L.
